CDs are fairly hardy but are far from indestructible. They are reasonably solid but overly flexing 
them can make them unreadable. They are not too sensitive to heat but will warp if left to bake in 
direct sunlight on a hot summer's day. CD media should always be cared for properly. The use of 
caddies or jewel cases will protect them; in general, the less handling, the better. 

 

Reading a CD-ROM 

Digital data is carved into the CD-ROM as pits (low spots) and lands (high spots). As the laser in 
the CD-ROM shines into the moving pits and lands, a sensor detects a change in reflection when 
it encounters a transition from pit to land or land to pit. Each transition is a 1. The lack of 
transitions are 0s. There is only one laser in a drive. Two are used here to illustrate the difference 
in reflection.  

 

IDE/ATA Interface 

IDE stands for Integrated Drive electronics. The name IDE is the more popular of the two, even 
though it is misleading which refers to putting the logic board with the hard disk much more than 
it has anything to do with the interface. The more correct name is ATA or 

AT Attachment

, which 

defines the standard interface as attached to an AT-style machine (which is the generic way of 
describing every PC since the old 8-bit XT). The IDE/ATA interface is 16 bits wide, just as the 
original IBM AT's data and I/O buses were.  
 

ATA Packet Interface (ATAPI) 

Originally, the IDE/ATA interface was designed to work only with hard disks. CD-ROMs and 
tape drives used either proprietary interfaces (often implemented on sound cards) or the floppy 
disk interface (which is slow and cumbersome). A few years ago it became apparent that there 
would be enormous advantages to using the standard IDE/ATA interface to support devices other 
than hard disks, due to its high performance, relative simplicity, and universality. 
 
However, because of how the ATA command structure works, it wasn't possible to simply put 
non-hard-disk devices on the IDE channel and expect it to work. Therefore, a special protocol 
was developed called the 

ATA Packet Interface

 or 

ATAPI

. The ATAPI standard is used for 

devices like CD-ROM and tape drives. It enables them to plug into the standard IDE cable used 
by IDE/ATA hard disks, and be configured as master or slave, etc. just like a hard disk would be. 

 
Note:

 When you see a CD-ROM or other non-hard-disk peripheral advertised as being an "IDE 

device" or working with IDE, it is really using the ATAPI protocol. 

 
Internally, however, the ATAPI protocol is not identical to the standard ATA (ATA-2, etc.) 
command set used by hard disks. A special ATAPI driver is used to communicate with these 
devices. This driver must be loaded into memory before the device can be accessed (some 
operating systems like Windows 95 support ATAPI internally and in essence, load their own 
drivers for the interface). The name "packet interface" comes from the fact that commands to 
ATAPI devices are sent in groups called packets; ATAPI in general is a much more complex 
interface than regular ATA. The actual transfers over the channel use regular PIO or DMA 
modes, just like hard disks, although support for the various modes differs much more widely by 
device than it does for hard disks.
